6. The metabolic pathway of glycolysis could be considered as: A. A totally irreversible process such as gluconeogenesis B. A process where oxidative (i.e., aerobic) phosphorylation occurs C. A reducing process that forms NADPH D. A process where fructose 6-phosphate functions as a transfer point to other metabolic pathways E. A process where phosphorylation occurs at the substrate level (obtaining ATP) in the phosphofructokinase-1 (PFK-1) reaction 7. Glycolysis produces more energy from glycogenolysis than from free glucose because: A. Pyruvate accumulates B. Glucose is already phosphorylated after the action of glycolysis C. Glucose from glycogenolysis does not undergo glycolysis D. Glucose from glycogenolysis enters the Krebs cycle directly E. The branching enzyme releases glucose 10. The Cori Cycle is essential in a state of: A. Fast B. Hyperglycemia - high blood sugar C. Hypoglycemia - low blood sugar D. Optimal health E. Stress 11. A muscle cell is working extremely hard under conditions of low glucose and an anaerobic environment. One way to get your energy in that state would be: A. All mentioned below B. By means of lactate dehydrogenase C. Through glycogenolysis D. Stimulating gluconeogenesis in the liver

Step 1
The metabolic pathway of glycolysis could be considered as: Glycolysis is a process where glucose is broken down into pyruvate, and energy is released in the form of ATP. It is not a totally irreversible process, nor does it involve oxidative phosphorylation. It Show more…
